The Construction And LCA Of The BNDES

In order to save fossil energy and improve the system efficiency,a new distributed energy system based on biomass and natural gas (BNDES) was promoted. Biomass was used to replace some of natural gas as the main fuel of the BNDES system. The concept design of BNDES and analysis of primary energy rate ware also presented. The life cycle assessment was carried out to assess the BNDES and a CCHP system based on natural gas. From the result it was drawn that the cost,the energy source consumption and the invironmental impact load of the natral gas system ware more than the BNDES.
